In the Hershey Chase experiment components of bacteriophages were labeled with radioactive isotopes of sulfur and phosphorus What was
the Hershey-Chase evperiment designed to determine?

Answers

Answer:

c

Explanation:

It was designed to determine whether the genetic material of the bacteriophage (a type of virus that infects bacteria) is made of DNA or protein.

What was  Hershey-Chase experiment?

The Hershey-Chase experiment, also known as the "Blender Experiment," was a classic experiment in molecular biology that was conducted in 1952 by Alfred Hershey and Martha Chase. It was designed to determine whether the genetic material of the bacteriophage (a type of virus that infects bacteria) is made of DNA or protein.

In the experiment, components of the bacteriophage were labeled with radioactive isotopes of sulfur and phosphorus. The labeled phages were then used to infect bacterial cells, and the cells were subjected to various treatments to separate the viral components from the bacterial components.

The results of the experiment showed that the genetic material of the bacteriophage was made of DNA, not protein. This was determined by the fact that the labeled DNA, but not the labeled protein, was able to enter the bacterial cells and infect them. This experiment provided strong evidence for the "central dogma" of molecular biology, which states that genetic information flows from DNA to protein, but not the other way around.

What are disadvantages of the "Aoudad"?
PLEASE ANSWER ASAP!!

Answers

Answer:

Anecdotal reports suggest aoudad out compete native big game species for food, water, and cover as well as act as a disease reservoir on Texas landscapes. If significant overlap for resources and space are occurring among aoudad, desert bighorn and mule deer, aoudad could outcompete and outgrow native populations.

Explanation:

Aoudad are a hardy desert sheep, native to the coastal and some inland mountains of northern Africa. While considered vulnerable in their native ranges, aoudad are abundant in the mountains of the Trans-Pecos. Little is known about their ecology in their newfound ranges, though considerable evidence suggests that they are susceptible to numerous diseases which affects native wildlife.

Which best describes the way a sound wave is sent through the radio?

sound wave → radio wave
radio wave → sound wave
radio wave → sound wave → electrical signal → sound wave
sound wave → electrical signal → radio wave → sound wave

Answers

The answer is sound wave-electrical wave-radio wave

Sound waves propagate from the sound source. The sound through radio comes through the electrical signal, radio wave, and sound wave. Thus, option D is correct.

What is a sound wave?

A sound wave is an acoustic wave that travels through a medium through the disturbance of the particles in a longitudinal direction. A few examples are radio, whisper, rustling, etc.  

The sound waves in radio first get converted into the electrical signal that passes through the circuit of the radio that further gets transferred as radio waves.

These radio waves are the part of the electromagnetic spectrum that travels at a little less speed than light. The radio waves again get converted into sound waves as it leaves the system and reaches the ear of the organism.

Therefore, option D. sound wave → electrical signal → radio wave → sound wave is the correct order.

2) If the foliation on a rock is running north-south what direction is the tectonic pressure coming from?

Answers

Answer:

if the foliation on a rock is running north-south, the pressure might be vertical (for instance, up to down)

Explanation:

The pressure is the second most principal factor that influences metamorphic rocks. It originates from the weight of the own materials, their densities, and the deepness.  

Litostatic pressure originates from the weight of materials in the interior of the crust.

Pressure generates alignment of materials (foliation and schistosity) and mineral rotation.

There are different types of metamorphism.

Dynamic metamorphism is the one where pressure is the principal factor. It generates by tectonic conditions, and it presents mainly in failure or fracture areas. It provokes trituration and recrystallization of minerals.

Classification of the metamorphic rocks according to their structure:

GranulationRecrystallizationMetasomatismMassiveFoliation

Foliation refers to dynamic metamorphism, where pressures act and minerals orientate perpendicular to the pressure direction.

According to this concept, if the foliation on a rock is running north-south, the pressure might be vertical (for instance, up to down) while minerals' weight helping in the process of foliation.

If the foliation on a rock is running north-south, the tectonic pressure is coming from a vertical direction.

What is a foliation?

Foliation on a rock means continuous multi layering on a metamorphic rock.

These layers can be thin as a sheet of paper.

Foliation occurs when the plain or elongated minerals inside a rock are pressed together and aligned.

Thus, If the foliation on a rock is running north-south, the tectonic pressure is coming from a vertical direction.

“How might an energy requirement affect an individual who has a cancerous tumour?”

Answers

Answer:

Cellular respiration describes the series of steps that cells use to break down sugar and other  chemicals to get the energy we need to function.  Energy is stored in the bonds of glucose (like a stretched rubber band), and when glucose is broken down, much of that energy is released.  Some of it is captured in a form that can be used to do work in cells - a molecule called adenosine triphosphate or ATP. The energy that is not captured in ATP is usually given off as heat (one of the things that helps us maintain our normal body temperature).
